x+1\geq 0 x-2<0
For the quotient to be ≤0, one of the values x+1 and x-2 has to be ≥0, the other has to be ≤0, and x-2 cannot be zero. Consider the case when x+1\geq 0 and x-2 is negative.
x\in [-1,2)
The solution satisfying both inequalities is x\in \left[-1,2\right).
x+1\leq 0 x-2>0
Consider the case when x+1\leq 0 and x-2 is positive.
x\in \emptyset
This is false for any x.
x\in [-1,2)
The final solution is the union of the obtained solutions.
